There are two main variables in this experiment, dependent variable, and independent variable. The independent variable is the controlled scientific experiment, whose effects are to be tested on the dependent variables.

Step 2

Its value may vary if the conditions are not kept the same throughout the experiment. A constant variable does not change its state or value, even if the conditions in the experiment are changed. In scientific experimentations, constant variables and controlled variables are similar to each other.

In the given experiment, ...
